In Part I of this series I dissected a pig spine to demonstrate the risks of rotational movements like Russian Twists.  In Part II I talked more about crunches and why I think they’re a terrible exercise.

In light of all the controversy lately over Mike Boyle’s no squatting comment I thought it would be a shame if I didn’t include something on that subject as well.  Please watch and enjoy.

I should note that some people have commented previously that pigs do not stand upright so this doesn’t necessarily apply.  Unfortunately, when I asked my friends to use their spines them seemed unusually resistant to the idea.  The good news is that pig spines are a pretty decent model for human spines which is why many spine researchers actually use them in their research.

 As usual, please share your thoughts, comments, and questions below.
